About H04.02
H04.02 is the ICD-10-CM diagnosis code for chronic dacryoadenitis. It belongs to category H04 (disorders of lacrimal system), block H00-H05 (disorders of eyelid, lacrimal system and orbit) and chapter 7 (diseases of the eye and adnexa). It is a header code, so it can't be reported by itself; one of its 4 subcodes must be used instead.
Within H04.0 (dacryoadenitis), H04.02 is specifically for chronic dacryoadenitis. Related codes cover unspecified dacryoadenitis (H04.00), acute dacryoadenitis (H04.01) and chronic enlargement of lacrimal gland (H04.03).
To report this condition, pick the subcode that matches the documentation: H04.021 (right lacrimal gland), H04.022 (left lacrimal gland), H04.023 (bilateral lacrimal gland) and H04.029 (unspecified lacrimal gland).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
